Application filed January To all whom it may concern:

Be. it known that 1, WILLIAM B'onron VVnsoorr, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts. have inve' certain new and u'sefui inipro in Apparatus for Heating Coated of which theiollowing is a specification.

This invention relates to apparatus for treating coated fabric which. is used to inforce' insoles of the gem type. The fabric used for this purpose is coated on one side with a suitable preparation cit-material which "may be rendered sticky by heat. it is the general practice to coat a. sheet or strip of fabric on one 516 and to roll the fabric after the coating l dried andtrans port it in rolls.

lhe apparatus to which the present invention relates comprises means for porting a roll of coated fabric, means for drawing'out the fabric from the roll. heating element whereby the coating material is rendered sticky, and means for holding the fabric against the heating element with suitable tension or for supporting it out of contact with the heating element.

Numerous othcr features of the invention are hereinafter described and claimed and are illustrated upon the accompanying drawin gs.

On the drawings: Figure 1 represents a side elevation, partly broken away, of the heating apparatus designed for a single strip of coated-material. Fig. 1? represents an elevation of a device for excluding cold air from the heating space. Fig. 1" represcnts a vertical section through said device on line Z -b of 1.

T he apparatus show by Figs. 16 and 1'! may be disregarded until hereinafter pressly mentioned.

Referring to i s. 1 and 52., a curved heating surface is indicated at 20. T his surface is afforded by the outer side of a sheet of metal Whose side ed es are supported by curved angle strips 21. (Sec Figs. 2, 3 and 4-). The strips 21 are secured to the inner sides of segmental strips Which form the side *alls of a chamber for containin insulating material 23. The curved inner wall of. the chamber is indicated at Qei. lhcse elements are supported by legs indicated at 25. The plate 20 extends through an arc of approximately ninety clegreesand itis interiorly heated by electric conductors 2G. The conductors are contained in the chamber formed by the members 20, 21, 22 and 24 and they are held against the inner rent. Jest 1 29% is suit- 11 TEPYQSGHLS an end elevation,

gages the arm 65 with the result of lifting the feed points before imparting reverse nection 72, so that it will be adapted to turn,

movement to the slide. When the treadle is depressed to impart feeding movement, the arm 65 is released by the stud 55 so that the spring 61 may act to press the feed points into operative engagement with the strip.

An adjustable abutment 68;is provided for varying the initial position of the feed slide, to'the end that the length of feeding movement may be varied. This abutment eccentrically affixed to a stem 69 which is adapted to turn in a bearing in the feed table. The abutment 68 arranged, as shown by Figs. '11 and 12, to be engaged by one of the ears 56. The outer end of the stem is threadedv and is provided with a clamping nut 70. A handle 71 is loosely mounted upon the stem between the nut and an adjacent face of the table. The handle is connected to the stem by a pin-and-slot conthe stem and at the same time be adapted to slide longitudinally of the stem and be clamped against the face of the table when the nut is set up tightly. In this way the abutment 68 may be tightly clamped against 1 a fate 73 of the table.

The tension exerted upon the strip by the feed points acting in conjunction withthe frame and cover, and is bent sum1ng, of course, that the cover 36 is in the pos1tion represented in Figs. 3 and 4. It is desirable to maintain this tension of the strip when the feeding points are moved in the reverse direction and while they'are stat1onary,'in order that the strip may be a 7 held against the heating plate with sufficient "=40 tension to conduct the heat to the coating material upon its outer surface. For this reason the cover 36 is provided with means adapted to engage the strip to maintain the tension created by the feed joints.

Referring to Figs. 1, 3 and 3, an open rectangular frame 74 is secured to the under side of the cover near the delivery end thereof. The strip is threaded through this frame and passes over a rock shaft 75 whose ends are journalcd in the frame. The rock shaft is'provided with sharp pointed members 76 which are adapted to be moved to and from. engagementwith the under side of the strip and to prevent retrograde movement of the strip when they are engaged. One 'ipr more springs 77 coiled about the rock shaft normally press the points downwardly or away from the strip. A lever 78 is aifixed to the rock shaft and extends upwaridly through a slot 79 (Fi 9) in the literally and downwardly, as shown best byFigs. 3 and 5. The free end of the lever is adapted to he engaged by a hook 8O atone. end of a rod 81 which is movable longitudinally.

The rod is adapto be operated by the feed slide when is latter is advanced to its foremost position, the purpose of lifting the retaining points 76 into engagement with the strip. The rod 81 is mounted in bearings 82 on the feed table, and its for ward end is bent inwardly as indicated at 83 (Figs. 9 and 10) in position to be engaged by the frame 60. A springiie attached to the rod 81 and abutting against one of the bearings 82 normally moves the rod in a direction opposite to the direction of feed. When the frame 60 strikes the end 83, the hook S0 acts upon the lever 78 to lift the points 76. 5 As soon as the tension on the strip is relieved by the feed points the stri settles back upon the retaining points, which are thereafter held up by the strip. The retaining points remain in opera-- tive engagement with the strip until the strip is once more fed forward, whereupon When the cover is again placed upon the heating apparatus, the lever 78 moves back into operative relation with the hook 80 so that-it will be in position to be operated by the hook when the rod 81 is again drawn forward. 7 V

4 Figs. 1a and 15 illustrate retaining points which may be employed in substitution for the points 76. Referring first to Fig; 14, the retaining points, one of which is indicated at 76, are affixed in a frame 74 in such manner as to engage the under or uncoated side of the strip. Retaining points aflixed in this manner are adapted to maintain the tension of the strip equally as well as the movable points 7 6, but they would be quickly worn away by the friction of the strip. A, comparison of the points 76 and 76 will show that while the latter are always in position to be engaged by the strip, the former are affixed to a rock shaft 7 5 and the rock shaft is mounted in a frame 74: in such manner that the points will engage the upper or 7 aerial, In practice, the innersoles var r i is drawn for ncient to cepres ';he

As soon as slacicened bf, the reading means, L 76 acts to throw the retainin observed that the lei-aiming poinas in this form cooperate with a portion of the frame 14 whereas in the two forms previously scribed l e pressure of the strip J? against points is due wuoli lo the s'l'rip, he lower end of (he cover 33' or with a device which adap'ied the coaled strip 27 at a point where ing has nol; been soflened. This presws against the strip on the plate and PI'QYlflll-S a draft of cold passii over that portion of the strip which is upon the plate. The details of construction of this addilional tension device are shown of; Figs. 1. and '1 (Sheet l). connected to the inner side of the cove i the manner of a hinge, being; pivohl mounted upon a pin or rod 86 which ried b v lho cover. Springs 87 coiled about the rod act, upon the plaie 85 to "ioiinaily swing its free away from ihe cover to the posilion shown by Fig. l and also by 1.

The cover in (his insl'ance is UL suilicicnt width to 0111- brace both slii'ips of coated nial'erial, the ex :zcl widlh of the cover being: shown in Fig. 17 by the side flu? '3 PM which are adapled lo lie onisidc the iciiical walls 2 22 ol the casing in which (he healing llUJlIOIli' is conl'ained. The cover is provided wil'h two sets of guiding devices such as lhose described, for guiding the strips and for supporting them when the cover is lifted. The additional guiding devices .lor the strip 27* are indical'ed at 35*, and the zulditional retainpoinl's for (he strip are indicated at 76*.

The cover 36. being" provided with sliding eonncclions sumiorled hv the lifling levers, is adapted to be shifted laterally when it is raised from the healed 'l-leinenl. As shown by Fig. 17, the clips or strips 4-1- which are secured lo (he cover surround lhe transverse rod which supported by the operating lever. 'Ill'le members llare free lo slide upon the rod. The lower end of the cover is adapted lo slide in like manner upon the rod 4:6.

The arms 30 and 210K- \Yllllll su port the rolls of coated material are connected by suitable 'conneclions wilh the cover 30 so that they and the cover may be shifted simullanemisly to pla e the desired strip of coated material in operative posilion. These connections, which are shown best by Fig.

- the arms 30-, and the upper end of which is connected by a pin-and-slot connection with. the cover 36. In the form illustrated, the bar 89 is formed with a vertical slot 90, the cover is provided with e horizontal pin 91 which extends through the slot and, adapted to maintain operative connection between the bar and the cover, whetl cover be lifted or lowered upon the he element. Strips or bars 92 connect the 89 with the outer'arms and 30 to the bar 80 and prevent it from tipping et orally, so that the cover 36 and. supporting means for the rolls 28 and 28" will move in unison. The bar 89 is held in upright position between a transverse connecting bar of the framework and a strap 94' secured to the bar 93. The bar 89 is provided with a handle 95 by which the laterally movable elements may be shifted.

The only rearrangement of the apparatus required to place the unused strip in operative position to detach the strip which not desired front the feeding means rior to shit 'ng the and to insert the desired strip tl'irough the feeding frame after the str os have shifted.

Duplicate connections ere provided for operating ti YO tension-retaining devices, As shown by Figs. 9 and 10, a rod 81* si-n'iilar to the rod 81 is mounted upon the teed table These two rods are disposed on -opposite sides the feeding slide. The rod 81 has a hoe; 80 similar to the hook 80, and a. lateral extension 83- similer to the tiztensio 83 and adapted to be engaged in the some manner by the feeoing frame (30. The rod 81 is adapted to he used when one strip is in operative position and the rod 81* is adapted to he used when the other strip is in operative pos' n. The points 76* which ongage the strip 27" are adapted to he'operated in the manner explained in conjunction with the points The operating lever for the points '76 is indicated at 78" in Fig. 17. When the strips are shifted to place the strip 27* in operative position, the operating lever 78* is shifted so as to stand in cooperative relation with the heel: 80, while at the some time the lever 78 associated with the strip 27' is removed from cooperative relation with the hook 80.

The supporting frame for the heating eleis provided with. e. rheostst which is illustrated conventionally and it". flies d at The rheostat is provided for control ling the current'hy which the heating coil is heated. Fig. 6 represents d of one arrangement of wiring ing coil. In this form the coil into two secti0ns,'both of which may i when the current is not directed through the rheostat, and one of which is out out when the current is directed thronghthe rheostat.
